Fifteen years ago, Satine (Nicole Kidman) and Christian (Ewan McGregor) played out their heartbreaking romance in "Moulin Rouge."

Fifteen years ago, Satine (Nicole Kidman) and Christian (Ewan McGregor) told a heartbreaking story of a courtesan and a poet who can't make their love last in Baz Luhrmann's "Moulin Rouge."

The film, which opened on June 1, 2001, was set in 1900 Paris, but featured modern music - a trend of Luhrmann - that moved the plot from romance to despair amid gaudy costumes and outlandish characters.

While you celebrate the greatest thing you'll ever learn, we'll rank the best musical numbers from the heartbreaking movie:

"Can Can"

We're pretty sure this is what it looks like to trip on acid, and it's a fabulous introduction to the eponymous Moulin Rouge in all of its gaudiness.

Among the dizzying array of costumes on the Can Can dancers are Marie Antoinette, a French maid, a dominatrix and a schoolgirl.

Musically, the scene combines "Lady Marmalade," performed by Christina Aguilera, Lil' Kim, Mya and Pink, and Nirvana's "Smells Like Teen Spirit" as Christian gets his first taste of his new world.

"Sparkling Diamonds"

Satine's first appearance is about looking and not touching, the girl you can only get if you can afford her.

With diamonds and cash being thrown about without care, both Christian and the Duke are told of the plans for them to woo the redhead as she takes what she can from her desperate fans.

"Spectacular Spectacular"

After the Duke interrupts Satine and Christian, the lovebirds - and all of their friends - are forced to put on an impromptu pitch for their show, "Spectacular Spectacular," to explain their meeting.

The hectic, flurried performance is a fast-paced delight that promises elephants, bohemians, Indians and courtesans.

Even the Duke, in all his confused, can't turn down the promise of profits.

"El Tango de Roxanne"

Everything works for this song-and-dance number: the narcoleptic Argentinian's deep, demanding voice as he sings Sting's "Roxanne," the fiery tango, the shadowy lighting.

Christian's version of NiNi's "Legs-in-the-Air," on the other hand, bookends the Duke presenting Satine with an elaborate diamond necklace, only to have it ripped away when he realized he doesn't actually have her heart - or attention.

"Your Song"

Look, "Your Song" is what it is: sappy and swoonworthy.

McGregor has the voice to pull off the solo ballad and the look of pure adoration to keep the performance from dipping into overwrought, even if the couple dancing in the clouds is too much for you.

"Come What May" (reprise)

We've already heard "Come What May" once, but it's the reprise that's the best performance of the secret song.

While Satine manages to win Christian back in the finale of "Spectacular Spectacular," the Duke has finally had enough of the illicit affair and signals for his bodyman to kill Christian and put an end to the romance once and for all.

Good thing Toulouse's aim - while not on target - is enough to knock away the gun.

Live theater, folks.

"Hindi Sad Diamonds"

Zidler's performance of "Spectacular Spectacular" gets more absurd the more we see it, and by the time it actually hits the stage for a live audience, the colors and noises are almost overwhelming.

Toss that in with Satine showing symptoms of the consumption that will eventually kill her, the Duke's obsession growing and his bodyguard skulking around backstage and you have a lot going on.

"One Day I'll Fly Away"

Kidman's voice isn't the strong suit of "Moulin Rouge," and it sounds especially breathy as she dreams of a life away from corsets and romance sold to the highest bidder.

The set is gorgeous, full of golden lights and bold colors, but even the hint of a future for her and Christian isn't enough to put it at the top of our list.
